FES Sensor Technology Hydrogen-Sensor NO2-SW 12C

NO2‐SW I2C is a semiconducting nitrogen dioxide sensor with a tungsten oxide based sensor element and is based on a conductometric operation principle. It contains a digital temperature sensor and an EEPROM for an advanced control of sensor characteristics in a wide temperature range of ‐40 to +85°C.


  • Sensitive detection of nitrogen dioxide levels in the sub‐ppm in air
  • Semiconducting tungsten oxide layer
  • Good response and recovery times
  • Applicable in relative humidity (rh) between 0 % to 100 %
  • On‐chip temperature Pt1000 element
  • On‐chip platinum heater
  •  Industrial temperature range from ‐40 °C to +85 °C
  • On‐board digital temperature sensor and EEPROM with I2C®bus connectivity
